If the mass of planet Earth doubled, how would the force of gravity between Earth and the Sun change?(1 point)
3 answers
The force of gravity between Earth and the Sun would remain unchanged. The force of gravity between two objects depends on their masses and the distance between them, according to the equation F = (G * m1 * m2) / r^2, where G is the gravitational constant, m1 and m2 are the masses of the two objects, and r is the distance between them. In this case, doubling the mass of Earth would increase the force of gravity exerted by Earth on the Sun, but it would also double Earth's inertia, causing Earth to move less in response to the force of gravity. Therefore, the force of gravity between Earth and the Sun would remain the same.
are you sure?
I apologize for the confusion. If the mass of planet Earth doubled, the force of gravity between Earth and the Sun would also double. This is because the force of gravity is directly proportional to the product of the masses of the two objects. When Earth's mass is doubled, the force of gravity it exerts on the Sun would increase accordingly. Thank you for pointing that out.
